IMPROVEMENT IN RAKING AND BINDING ATTAcHMENTs To HAR- l vBsTERs.

Specification forming part of Letters Patent No. 37,408, dated January 13, 1863.

To all whom it' may concern New York, have invented a new and Improved linking and Binding AttachmentforI-llarvestv ers and I do hereby declare that the follow-` ing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figurc 1 is a side sectional view of my in- Y ventiou, taken in the line rv a', Fig.;2; Fig'. 2, a Y plan or top lview of the same Fig. 3, a section of a portion of the same,taken in theline y y,

,Similar letters oi' reference indicate corresponding parts in the several iigures.

The object of this invention is to obtaina raking and binding attachment which may be applied to a harvester, and operated from `the drivin gwheel thereof, so as to gather or rake up the cut grain from the platform into gavels, and'bind the same with a cord, the latter being tied with a knot so as to insure the firm binding oi' the sheaves.

The invention consists in the lpeculiar means 'employed for effect-in g the result above named,

and which will be hereinafter fully shown and described.

. p 'lo enable those-skilled in the art to fully understand and construct my invention, I -will proceed to describe it.

A represents the platform of a harvester,

. the part on which the cnt grain falls as it is cut by the sickle, and B is a rake which is placed in a transverse position relatively with the platform A. The head a of this rake is of bent or curved form, and is connected at its inner end 'by a joint o'r hinge, b, with a slide, C, the upper and lower edges of which. are fitted in grooves L b', in parallel bars c c, at the back part of the platform A. (See Fig. 7.) To the rake-head a there is attached an arm,

d, which projects over a guide, e, attached to the upper bar e, and this arm hasv a pendent Be it known that I, THEoDonE PALMER, of Catskill, in the county of Greene and-Stateof pin, f, attached to it, said piu extending down at the back of the guide c.

g Dis 'an endless chain, which works over two wheels g g, theaxes of which are nuprights h h at the back of the platform A.- These wheels g gare provided with teeth, which fit into the links ofthe chain D and prevent the slipping of the latter.` (See Fig. l.) 'lhe cha-inl) has a projection, t', attached telv one of its links, and this projection, as the chain D is operated, moves the slide C, and consequently the rake l, the projection 'z' comingl in contact with horizontal pins'j at the inner side of the slide G, and communicating al reciprocating movement to the rake, the projection t' acting against the upper pin j as the'former passes along above the wheels-g, and acting against the lower pin j as it passes along below the wheels g, (see Fig.`1,) which in' the projection i and pins j j are shown by dotted lines, and 'the direct-ion of the movement of the chain indicated by the arrowsll.V

lhe upper bar c, at the back of theplatform A, has two curved' oblique shoulders or ledges, k" k, upon it. v-'lhe'ledge 7c" is a fixed or permanent one,but theledge k" is a spring which the piu f of the arm tl'oilthe rake-head a can force out and com-pelfthe pin fy at the backward'movement-of the rake to follow-the ledge k" andpassdownunderneath the bar e. By this means the rakeA is elevated.- during 'its returlrmovenienas indicated inFig. 7, the pin f 'p'assingup by' the side of the iixed ledge 7c as the rake'. reaches the termination of its backward movement, so that the latter may assume allorizon'tal or working position at the commencement of its forward movement. .y The rakeB, just previous to the termination of its forward movement, is slightly elevated by means of a beveled bar, l, which `is at the back'of the guide e. This elevation oi' the rake `enables the teethotth'e rake to pass np a slotted inclined surface, m, on'the platfornnthe object of which will be presently shown.

The endless'chain D is operated bymeans of a toothed wheel, n, which is on the anis ofA `the front wheel g, and gears into a pinion, 0

on the driving-shaft It wiil be seenthat the elcvating'and lowering of the rakeB are ,due to the head abein connected to the slide C by the joint or hinge b.

G represents a shaft, which is fitted trans verselyin the platform A, and is provided toothed wheel', I, which is rotated by a pinion,

r, on the driving-shaft F. The india-rubber spring g has a tendency to keep' the curved teeth p down and below the inclined part m of the platform, and the cam H elcvates the'teeth p by coming in contact, at each 'revolution of the wheel I, with a curved arm, s, on shaft G.

' J representsa shaft, which is placed in a` frame, K, attached to the platform A. This shaft J has two curved arms or hooks, t 1 attached to it, which I term collecting-hooks.'

These hooks tifare also raised and lowered by the turning ofthe shaft J first in one direction and then in the other. The hooks t t are moved upward and outward by means of an india-rubber spring, L, attached to anarm, fu, on shaft lJ, and said hooks are' moved down- -ward by means of a'friction and ratchet clutch, M, and cam-proiections, c fu fr at-the inner side of the wheel I. The clutch M l is 'composed of a wheel, fw, which is permanently secured on the shaft J, and has a portionot' its periphery smooth, as shown at a', and a portion provided with ratchet-teeth, as shown -at b'. See Fi g. 4.) Thewheelw has an annular groove, c, made in it, and in this groove Van 'annular plate, d', is fitted and secured thereinby'two screws, c4 c', which pass through oblong curved slots f inthe wheel w, and through a piece of india-rubber, g', and a metalplate, h', (See Fig. 5.) The india-rubber gadmits of 'a certain degree of play ot' the annular plate d' in the Agroove c', the oblong curved slots f -admitting of the movement of the screws e.

These slots areV shown by dotted lines in Fig. 4. The lower part of the wheel zu has its pcriphery covered by a curved plate, i', which is attached to the frame K, and to the louter side of. the annular plate d there is secured a bar, j', one end of which is provided with a lip or projection, k', and the other end provided wi'th a Alip or projection, k", Said bar also has a pawl,

m', attached to it, against which a spring, it',

bears. Against ,these )ro'ectionsk k* the' cam-prqcctions c rf fr", at the inner side of the wheel I ,act.

On the frame It there is also placeda shaft., N, which has a pinion on its outer end. This shaft N is rotated intermittently by means of toothed segments l), attached to the outer side of the wheel I. 0n the shaft N there is keyed a cani, Q, which operates a curved lever,

R, which has an elastic cord,, at its end. On this shaft N there are also keyed two other cams, S S', one of which, S, operates an'arm, T, having a fork, p', at its front end, and an eye, q', the cord U, with which the sheaves are bound, passing through the latterand around a pulley, t", said cord being on a spool, t, on the frame K. The cam Sl operates a slide, W, which has a hook, s', at its front end, and this slide has an arm, t', projecting from it at right angles. This arm t extends back of a slide, a', which is iitted on a guide, c", and has a curved arm, 1v', attached to it by two screws, a* ax, which pass throughslots b bx, in said ar1n,int o the slide u. The back end of the arm w has an elastic cord or india-rubber spring, cy` attached to it, and there is also a guide, d, attached to the back end of said arm, said guide resting ou the shaft N, between the cam S andthe inner bearing e* of said shaft. X is a slide, which has a knife or cutter, Y, of curved lform attached to it. lThe back end' of the slide X is provided with a notch, fx, underneath which the arm't of the slide XV catches when the latter is dra-wn back. 0n the frame K there is secured' a small ledge or lupright projection, gX which at a certain time liberates the slide X from the arm t', and4 admits of a spring, It", throwing said slide Xforward. Z is an arm, which is attached to the frame K, and has a small projection or-knob, ix, at one end, said projection or knob being i'n line with the hook s of the slide NY.

Then the machine is in operation the endless ehain D moves in the direction indicated by 'thearrows in Fig. 1,and the rake B, when movedbysaid chain toward the elevated part ,m ofv the platform A, rakesthe cut grain towardl said elevated part m and over the curvedteeth p, which are below the slotted elevated part m ot' the platform, while the rake B is thus opera-ting. J ust previous to` the'termination ofthis movementof the rake 'B,the hooks `t t are 1nadeto descend, and

serve as a bearing or bed -to receive the cut grain., raked up by-the rake. This .movement 'of the teeth' is effected -by the action of the cam-projections a 'v/v onthe lips or projections k kof the bar j', said cams effecting the downward` movement `ofthe hooks and retaining the-same ina downward position a necessary length of time to admit of the sheaf being bound. When the hooks t t are .down the teeth p are elevated in consequence of the cam E acting against the curved. arm s on shaft G, and the--gavel to be bound is there embraced between the hooks t t, and the curved teeth@ andthe cord Uwill be around said gavel,-the oute'r end .of the cord being grasped by'a cl'a'mp,'af X, which is attached to a slide, A', tted in a slot at the outer'end ot" the'central tooth pf This slide A is provided with an eye, b* .,into which the frontend of the arm T passes. An said arm` and thevslide A are raised by the action of the cam S, the arm and slide d rawin g the cord'snugly around .tre-Wye v1. n

the gavel. The clamp ax x of the slide A'passes into the fork p of the armvl. When the arm T is raised the lever R is operated by the cam the lever winding the cord U around the! projection or knob i* of the arm 'Z, and the hook s of the slide W is then shoved forward and backward by the cam s", the hook in its backward movement drawingthe cord through the loop, and thereby forming the knot, and the cutter Y cuts o the cord above the knot,

the arm 1c serving as a bearing for the cord` while being cut. As the slide W reaches the.

termination .of its backward movement, 'thel ledge or projection gx throws up the notch f" of the slide X-free from the arm t of *slide W,

`and the spring It* throws the knife or cutter Y. backto its original position. The hookst t other parts are in readiness to receive a succeeding gavel.

'Vhen tll'e hooks t t are first actuated, the shaft J is turned, directlyl through the medium of the bar j', annularplate d', and the indiarubher g. AThis india-rubber g', on account of its elasticity, will yield or give in ease of a gavel of undue `size being `between the lhooks t t and. teeth p, and admits of the bar j andplate d( turning without communicating motion to the wheel M and shaft N. During this movement of the. bar j', the pawl m works over the curved plate 17 below the wheel M;

but when the pawl m' reaches the teeth b of wheel M, the latter, and Vconsequently' the shaft J, are turned with a positive movement. This arrangement insures an equal pressure of the hooks tt on all the gavels, and prevents any /of the lparts connected with the operation of the shaft J from being subjected to any undue strain,'`a contingency which would be'liable to occur in case of gavels of undue size being embraced by the hooks t and teeth p.

'Having thus described my invention, what I claim as new, and dcsireto secure by Letters Patent, is-

1. The combination of the rake B, endless chain D, guide e, ledges k k, and beveled bar l, all arranged,vas shown', to'admit of .the rake B operating as and for thel purpose herein set forth. d

.2. The manner, as shdwn,V of -Aoperatin g the hooks t t, or turning the shaft J thereof, to wit, by means of 'the wheel M, provided with a smooth and toothed periphery, the plate d connected with the india-rubber g', the bar j prvided with the pawl m', and the cam-pro-` jections u u 'v" on wheel I, yall arranged as and for the purpose herein set forth.

.3. The combination and arrangement of the lever R; arm '.l, hook s', cutter Y, arm Z, with the projection or knob i* at its end, arm fw',

and the slide A', on the central tooth p of the shaft G, allarranged to operate as and for the purpose specified.
